~900$ for 20 GH ? LOL

1000$ for 20G/h, without a heat sink and cooler. This is getting to the point of scamming people.
Almost the same if i ask 2 BTC for mine Bitburner fury (50Gh).
Prices are way to high, no more interest for me.
If you could find cheap asics we will do a cheap devices for you.
As a manufacturer we are interested in a wholesale that is why retail price is little high. But you may find resellers selling our miners with heatsinks and psu

Also lets get back to definition of "scamming". If we promised 30Gh and sent 20Gh units we were scamming, if we promised couple of months for product preorder and took money for a year we were scamming but we are just selling devises for our price. So if you don't like it just pass by and try to find another offers.
